The brain's default network: origins and implications for the study of psychosis

The brain's default network is a set of regions that is spontaneously active during passive moments. The network is also active during directed tasks that require participants to remember past events or imagine upcoming events. One hypothesis is that the network facilitates construction of mental models (simulations) that can be used adaptively in many contexts. Extensive research has considered whether disruption of the default network may contribute to disease. While an intriguing possibility, a specific challenge to this notion is the fact that it is difficult to accurately measure the default network in patients where confounds of head motion and compliance are prominent. Nonetheless, some intriguing recent findings suggest that dysfunctional interactions between front-oparietal control systems and the default network contribute to psychosis. Psychosis may be a network disturbance that manifests as disordered thought partly because it disrupts the fragile balance between the default network and competing brain systems

Frontally Mediated Control Processes Contribute to Source Memory Retrieval

AbstractRemembering is a cognitively demanding task that requires the strategic selection of information from memory. In this issue of Neuron, Dobbins et al. present functional MRI (fMRI) data that shed insight into the specific, dissociated contributions of frontal regions to remembering
